I just acquired a 1998 Lund Tyee model 1950. It has a walk through windshield. The walk through piece is currently not attached. It has built in hing pieces the fit over pins permanently attached to the side piece. It appears there are two black plastic pieces that slide into place to put pressure against the pins and hold the it in place. One of these is missing. I cannot seem to locate anyplace to purchase this little piece to correct the problem. Does anyone have any ideas where I could buy this? I love this boat after I replaced the rotten transom!
